INHALING APPARATUS.

Specification of Letters Patent No. 11,97 6, dated November 21, 1854.

To all whom it may concern:

Be it known that I, SAMUEL H. T. TILGH- MAN, of Snow Hill, in the countyof VVorcester and State of Maryland, have invented a new and usefulapparatus for the inhaling of medicated air, called Tilghmans MedicalInspirator; 'and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing, forming part of thisspecification, in which- Figure 1 is a top view of the apparatus. Fig. 2is a vertical section on line of Fig. 1.

Similar letters of reference in the several figures denote the same partof the apparatus.

My invention consists in the construction and arrangement of the hereindescribed apparatus, which will be understood by reference to thedrawing, in which A is a portable furnace over which is a wider vesselB, within which is the distilling vessel C which contains the herbsintended to impregnate the air inhaled by the patient. Upon the stand Sis a vessel D containing a worm a which communicates by the pipe b withthe distilling vessel C and whose upper extremity terminates in theflexible tube c. Under the stand S is the bellows F the nozzle (Z ofwhich is connected with the tube f leading to the distilling vessel C.At the extremity of the tube c is the mouth piece m having the twovalves e and z' t-he former opening upward and the latter openingoutward. The construction and arrangement of the several parts need notbe precisely as herein set forth but may be varied in detailv providedthe main features are not departed from.

The object of this apparatus is to enable persons with diseased lungs toinhale medicated air in a comparatively dry state; its operation is asfollows-The herbs are distilled in the vessel C by the well known meansof placing a fire in the furnace A and filling the vessel B with water.The vessel D is lalso tilled with cold water for effecting the partialcondensation of the medicated vapor.

When the apparatus is ready for operation, the patient places the piecem in his mouth and by inspiration opens the valve and receives themedicated air from the tube c. The succeeding act of respiration closesthe valve z' and opens the valve e giving the air from the lungs a. freepassage to the open air; the next inspiration closes the valve e andopens z' as before and so the valves are alternately Opened and closedduring the operation.

`Should the lungs of the patient be weak the bellows Fis brought intorequisition, air being forced through the tube f to the vessel C, andthence to the lungs as above described.

The. medicated vapor from the vessel C becomes partially condensed inpassing through the worm a and runs back to the said vessel in a liquidform; while the air which enters the lungs of the patient is thuscomparatively dry and impregnated to some extent with the medicine.

Of the effect of the inhalation upon the patient it is not herenecessary to speak as this application merely refers to the constructionand arrangement of the apparatus by which the air reaches the lungs in acomparatively dry state, and by which they are assisted in theinspiration.

Having thus described the construction and operation of my apparat-us, Iexpressly disclaim the parts comp'osing it separately considered.

WV hat I claim as my invention and desire to secure by Letters Patent,is-

The combination of worm a, tubes c and f mouth piece m, bellows F anddistilling vessel C constructed and arranged substantially as set forthfor furnishing medicated air in a comparatively dry state and assistingthe respiration of the atient in inhaling it as herein before speci ed.

In testimony whereof, I have hereunto signed my name before twosubscribing witnesses.
